MEMBERSHIP UPDATE AND TREASURER'S REPORT Michael Mirmak reported that he got the summary of January expenses from the GEIA. No invoice for the second portion of the parser payment has been received. There are 20 confirmed memberships for 2005, and he is still checking on a few more. Bob Ross asked who the new members were this year. Michael responded that new members are Fluent, Actel, Agere, AMD, Silicon Image, ICS, and Xilinx. REVIEW OF MINUTES AND ARS Michael Mirmak reviewed the minutes of the January 28, 2005 IBIS Open Forum teleconference and the January 31, 2005 DesignCon Summit meeting. Bob Ross mentioned finding a spelling error in the January 28, 2005 minutes of Ralf Bruening under External Progress. The minutes of the meetings were approved with the noted editorial change. PRESS AND WEB PAGE UPDATES Syed Huq reported that recent updates were made on the events page. He would like Bob Ross to check over the site. Bob accepted the AR. Bob mentioned seeing an article in the February 14, 2005 EE Times magazine on "IBIS can help Model Gigabit Pre-emphasis". The article was written by Arpad Muranyi, Michael Mirmak, and Donald Telian. NEW MODELS AVAILABLE, LIBRARY UPDATE Michael Mirmak reported for Lance Wang that there has been no new model activity. MISCELLANY/ANNOUNCEMENTS None. OPENS FOR NEW ISSUES Bob Ross requested that DAC planning be discussed as well as a discussion on Michael Mirmak's plans for coverage during his time off. MAILING LIST ADMINISTRATION Bob Ross reported that things have been working normally. The eda.org mail list administrator has been looking at editing of the email archives to remove the ability of spammers to find email addresses from the archives. INTERNATIONAL/EXTERNAL PROGRESS Michael Mirmak gave a presentation on Monday, February 14 to the Verilog-AMS working group. During the teleconference, questions were posed regarding which features of AMS that IBIS is interested in using. Feedback from the IBIS group was requested regarding implementation of table model functions in Verilog-AMS. There are no plans to report to that working group again in the near future. Michael received another invitation to attend the VHDL-AMS working group meeting on Wednesday, March 9 at DATE. SUMMITS - DesignCon IBIS Summit, January 31, 2005, Santa Clara, CA Michael Mirmak summarized the DesignCon 2005 IBIS Summit meeting. 54 members officially attended as logged with the GEIA. Many expressed specific interest in BIRD95. There was a very full agenda, and Michael would like to keep this level of interest at future summits. Bob Ross thanked Cisco and Cadence for sponsoring refreshments. Michael thanked Mentor for taking care of the booth. The IBIS sign was missing from the booth, so this needs to be replaced. John Angulo will talk with Michael offline about where to store the booth in the future. - DATE European IBIS Summit, March 11, 2005, Munich, Germany DATE 2005 will take place in Munich, with a Summit planned for Friday, March 11. Ralf Bruening of Zuken has concluded making arrangements for the room and other logistics. The third announcement was sent out. Zuken, Mentor, Cadence, and Seimens are sponsors. Several papers are planned. Bob Ross mentioned that on Thursday, March 10 there is a PCB symposium at DATE that is free to those who register with DATE. Eckhard Lenski will make a presentation on "Support of IBIS Models in a Modern Design Flow." Bob said that the final agenda should be sent out on March 4. - JEITA IBIS Event - Japan, March 24, 2005, Tokyo, Japan Michael Mirmak reported that travel arrangements are being finalized for the JEITA IBIS event. People can contact Michael Mirmak with questions. - DAC IBIS Summit Bob Ross reported that DAC is held in Annaheim, California from June 13-17. A room needs to be reserved for 30-35 people. Tuesday, June 14 would be the Summit. It needs to be discussed at a later time the possibility of having an exhibition booth to increase participation and visibility. John Angulo said that Mentor is looking into the room reservations already. Sponsorship is essential for this and welcome. Sponsorship opportunities for all these Summits are still available, with sponsors receiving free mentions in the minutes, agenda, and other announcements. IBIS ANSI BALLOT STATUS Randy Wolff reported that the GEIA had sent results of the IBIS 3.2 reballoting. Of 23 active members that ballots were sent to, 20 members responded. All responses were positive, so the ballot passed successfully. Michael Mirmak thanked everyone for responding to the ballots. S2IBIS3 STATUS Ambrish Varma reported that he added support for Eldo simulation. He also added the algorithms for clamp subtraction. A final version will be posted on the website soon. Bob Ross asked if both clamps are subtracted for open drain and open source driver cases? Ambrish believes that all models are handled similarly, but he will check on that. S2IBIS3 beta executables can be downloaded from: http://www.ece.ncsu.edu/erl/ibis/s2ibis3/s2ibis3.htm Feedback on the current version is appreciated and encouraged. IBIS VERSION 4.1 PARSER STATUS Bob Ross reported that he is meeting with Jon Powell tomorrow. They are ready to release the code as version 4.1.0. ICM SPECIFICATION AND PARSER STATUS Michael Mirmak reported that we are starting the reading process for ICM 1.1. The first official reading will be at the next meeting. A cleaned-up copy of the specification will be released before the next meeting. IBIS QUALITY COMMITTEE Bob Ross reported that the committee met February 15th. The next meeting is March 1. The committee is deciding which additional checks they would like recommend as additions the parser and the quality document. IBIS MODEL REVIEW COMMITTEE No report. FUTURES AND COOKBOOK COMMITTEES Michael Mirmak reported that the committees met yesterday. The Cookbook committee reviewed the latest draft of the cookbook, and it looked good. The Futures committee discussed ICM links and BIRD95. The committees meet every two weeks. Recent committee material is stored at: http://www.ibis-information.org/futures/ NEW ADMINISTRATIVE ISSUES Michael Mirmak will be on sabbatical shortly after his trip to the JEITA IBIS event. He will be out of contact March 25 through the month of April. He may be available for the May 3 meeting. Syed Huq will run the meetings in Michael's absence. All invoicing issues with the GEIA should be taken care of before Michael leaves. BIRD96: [MODEL SPEC] AND [RECEIVER THRESHOLDS] ORDERING Randy Wolff mentioned that he had not received any comments expressing issues with the BIRD. No concerns were raised during discussion. There was a call for vote for inclusion of BIRD96 into the next version of the IBIS specification. The BIRD passed unanimously with the following vote tally: Cadence - yes Cisco - yes Intel - yes Mentor - yes Micron - yes Samtec - yes Siemens - yes Teraspeed - yes Xilinx - yes COMPLEX I/O, MACROMODELING AND IBIS 4.1 - EXTENDED DISCUSSION Donald Telian began the discussion. He asked everyone to open up the presentation file that Michael previously sent out the link for. The files referenced during the discussion are listed below. Donald noted that there is a rapid increase in transistor model usage currently. The industry as a whole recognizes IBIS as the best approach for behavioral modeling. AMS and Spice are appropriate languages for behavioral macromodels. He said that IBIS could offer the industry templates of how to use these languages to create models. Within the industry he found a definite unfamiliarity with the AMS languages. He stressed that the [External Model] Spice option was very important to discuss. Cadence's use of Spice macromodeling has made it easy to implement new keywords through macromodeling around a basic B-element. Donald suggested an improved IBIS 4.1 Spice option to give users the opportunity to do themselves what Cadence has done behind the scenes from the start. Michael Mirmak asked how this is different from AMS? Donald views them as complementary, that you can do it in whatever language you understand better. Syed Huq asked if behavioral Spice is a macromodel? Donald replied that behavioral Spice is narrower. Syed asked if runtime improvements over Spice are seen using Spice macromodeling? Donald said that the same improvement can be seen as using native IBIS. Ian Dodd mentioned that Spice is not necessarily slow, and that it all depends on the simulator. Donald said that Berkeley Spice is missing some important things. The key element missing is an IBIS driver (B-element). Also, parameter passing is missing. Donald said that IBIS 4.1 points to AMS, but where it supports Berkeley Spice, that needs to be replaced as Berkeley Spice plus the B-element, parameter passing, and table based EFGH elements. Itzik Peleg asked why not just support HSPICE? Michael Mirmak responded that it is not an industry standard, and we do not want to bless a particular tool through the specification. Ian Dodd said that his customers are interested in more Spice based solutions. Donald would also like to see the creation of an IBIS 4.1 complex I/O template repository. Further discussion will ensue at the Futures meeting and at the next teleconference.

I-t tables will remain as the core of BIRD95. Michael Mirmak said that the split up of the BIRD provides natural breaks between changes to the specification. ICM links and ICEM links are now separate BIRDs. Michael asked if we know all the pieces that need to be part of BIRD95.2. Bob Ross said that he will look at if Z_vddq pieces can be fit into this BIRD. Syed received email questions about core modeling from Norio Matsui. Arpad asked what needed to be done about gate modulation effects? Syed would like to see gate modulation as a separate BIRD. Arpad will pursue this. BIRD94: CLARIFICATIONS ON [DIFF PIN] PARAMETERS Discussion was deferred until the next meeting. IBISCHK4 BUG STATUS No report. ICMCHK1 BUG STATUS None to report. NEW TECHNICAL ISSUES None. NEXT MEETING The next IBIS Summit will be held March 11, 2005 at DATE. No telephone bridge is available. An Open Forum teleconference has been scheduled for March 11, 2005 from 8:00 AM to 10:00 AM US Pacific Time. The JEITA IBIS Event will be held March 24, 2005 in Japan.
